Security was tight in the northern district of Tai Po, close to the border with mainland China, where the fire engulfed seven towers.

The city is holding elections for the Legislative Council.

Residents are angry over the blaze that killed at least 159 people and took nearly two days to extinguish after it broke out on November 26.

The authorities say substandard building materials used in renovating a high-rise housing estate were responsible for fuelling the fire.

Authorities have launched criminal and corruption investigations into the blaze, and roughly 100 police patrolled the area around Wang Fuk Court, the site of the fire, early on Sunday.

Low turnout

A resident in his late 70s named Cheng, who lives near the charred buildings, said he would not vote.

“I’m very upset by the great fire,” he said during a morning walk.

At a memorial site near the burned-out residential development, a sign said authorities plan to clear the area after the election concludes close to midnight.

Beijing’s national security office in Hong Kong has said it would crack down on any “anti-China” protest in the wake of the fire and warned against using the disaster to “disrupt Hong Kong”.

China’s national security office in Hong Kong warned senior editors from a number of foreign media outlets at a meeting in the city on Saturday not to spread “false information” or “smear” government efforts to deal with the fire.

All voters need to come out

Publicly inciting a vote boycott was criminalised as part of the sweeping changes.

The number of registered voters for Sunday’s polls – 4.13 million – has dropped for the fourth consecutive year since 2021, when a peak of 4.47 million people were registered.

Seven people had been arrested as of Thursday for inciting others not to vote, the city’s anti-corruption body said.

Hong Kong and Chinese officials have stepped up calls for people to vote.

“We absolutely need all voters to come out and vote today, because every vote represents our push for reform, our protection of the victims of (fire) disaster, and a representation of our will to unite and move forward together,” Hong Kong leader John Lee said after casting his vote.

Hong Kong’s national security office urged residents on Thursday to “actively participate in voting”, saying it was critical in supporting reconstruction efforts by the government after the fire.

“Every voter is a stakeholder in the homeland of Hong Kong,” the office said in a statement. “If you truly love Hong Kong, you will vote sincerely.”

The last Legislative Council elections in 2021 recorded the lowest voter turnout – 30.2% — since Britain returned Hong Kong to Chinese rule in 1997.
